Wubi was born as an independent project and as such versions 7.04 and 7.10 were unofficial releases. Since 8.04 the code has been merged within Ubuntu and since 8.04 alpha 5, Wubi can also be found in the Ubuntu Live CD.

Wubi was made to help Windows users who are do not know Linux very well to try it out easily without losing data or other problems. Wubi can also remove Ubuntu from inside Windows.
